Dataset Description

This dashboard uses data from the publicly available SEER colorectal cancer dataset, provided by the National Cancer Institute.
Data were collected from hospital records and state cancer registries covering individuals aged 18 to 50 residing in Georgia.
The dataset includes case counts and population data aggregated by county and race group.
The analysis focuses on the time period from 2000 to 2010.
County-level incidence rates were calculated using standardized population counts and matched to geographic shapefiles for visualization.

Widget 1: Interactive Scatter Plot

This scatter plot shows the relationship between population size and cancer incidence rate in Georgia counties. You can hover over points to see detailed data, and use zoom/pan features for exploration.

Key Takeaways:

  • The majority of counties have populations under 500,000 and incidence rates between 5 and 20 per 100,000.
  • Larger counties show less variability in incidence rates, clustering around consistent values.
  • Counties with smaller populations tend to have greater variation, including outliers with very high rates, possibly due to data instability in low-population areas.

Widget 2: Interactive Incidence Map

This map visualizes colorectal cancer incidence rates across Georgia counties. The color intensity represents the rate per 100,000 people. You can hover over each county for more details.

## Simple feature collection with 159 features and 18 fields
## Geometry type: MULTIPOLYGON
## Dimension:     XY
## Bounding box:  xmin: -85.60516 ymin: 30.35576 xmax: -80.75143 ymax: 35.00066
## Geodetic CRS:  NAD83

Key Takeaways:

  • Colorectal cancer incidence is not evenly distributed across Georgia’s counties.
  • Several counties in central and southwestern Georgia display noticeably higher incidence rates.
  • The spatial distribution suggests that localized factors may influence colorectal cancer risk and deserve further investigation.
